Consider a wall that consists of two layers, A and B, with the following values: k subscript A equals 0.8 space w divided by m to the power of o c comma space L subscript A equals 8 space c m comma space k subscript B equals 0.2 space w divided by m to the power of o c comma space a n d space space L subscript B equals 5 space c m. If the temperature drop across the wall is 8 to the power of o c , the rate of heat transfer through the wall per unit area of the wall in w divided by m squared is

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
